I was introduced to an app called inaturalist and I like it so much! Basically, it is for recording wildlife around you, and it helps you identify what you observe, and it also lets knowledgeable persons identify what you have seen. For example, yesterday I saw a bug and was able to go "ooo nice shiny bug", and after consulting with my dad narrowing it down to "some kind of løpebille (ground beetle) but today a zoologist identified it for me as carabus morbillosus, yay! *shakes nearest person to shout: this is fantastic!*
